TEETER-TOTTER.

Specification of Letters Patent.

Patented Aug. 17, 1920.

Application filed October 10, 1917. Serial No. 195,730.

To all whom it may concern:

Be it known that I, THOMAS WALLACE, a subject of the King of Great Britain, and residing at Vabash in the county of Wabash and State of lndiana, have invented new and useful Improvements in Teeter- Totters.

Generally stated my device consists of a top board comparatively thin and reinforced along its sides by horizontal members attached at, or about right angles, to the top board, the whole supported centrally by an upright support terminating at its lower end in curved, boarded rocking base.

My object is to provide a teeter totter board so designed that it possesses all strength necessary for its purpose, yet is of such small weight that a child may readily move the device from place to place, also to give to the child a device that is attractive in appearance, simple in its manner of use, and compact in its construction.

Another object is to make a teeter totter that can be used on a soft or hard surface, such as wood, concrete, carpets, grass or sand. To achieve this purpose I devised. what is shown in these specifications as a curved rocking base.

Referring to the accompanying drawing:

Figure 1 is a side View of my teeter totter, constructed in accordance with my invention. Fig. 2 a vertical cross section on the line li -Z) Fig. 1. Fig. 3 is a side view of the teeter board showing the are C which gives the approximate radius of the curve of the rocking base 4, Figs. 1, 2, 3 and 5. Fig. 4 is a vertical cross section on the line L.- M. Fig. 3. Fig. 5 is a perspective View of the rocking support for the teeter-totter.

Referring particularly to the different parts, the same figures indicate the same parts throughout:

1 is the top board proper; 2 are side reinforcements for top board; 3 is a rocking support, having its lower ends slightly curved to admit of a teeter totter motion, and its upper ends attached to the re inforcing sides 2. 4: is a rocking base board pressed to the curve and attached to the bottom ends of the rocking support. The radius of the aforementioned curve approximates the radius that would be required to draw an arc of a circle passing through the three points F. D. E. Fig. 3. 5 are battens to give strength to the rocking support 3. 6 is a top member holding together in proper relation the sides of rocking support 3. 7 are holes "for the reception of bolts for attaching the rocking support to the sides 2. This construction makes possible the shipping of.

the teeter totter in a knockdown condition.

\Vhat I claim as new, and desire to secure by Letters Patent, is

r 1. A fulcrum rocking support adapted for attachment at its top end to a teeter totter board, and its lower end terminating in an unbroken boarded rocking base.

2. A fulcrum rocking support comprising two diverging sides and having the two converging top ends formed for rigid attachment to a teeter totter board, and its divergent bottom ends connected throughout by an unbroken curved surface, forming a rocking base.
